American heavyweight Tony Thompson believes that David Price lacks "knowledge" inside the ring.
Thompson faces Price on Saturday night after previously stopping the Liverpudlian inside two rounds, and the veteran has insisted that he will expose more of his opponent's weaknesses this time around.
The 41-year-old said in a press release: "David lacks knowledge and he can't have changed much in four months.
"He still has many weaknesses, and it might be a different one which I choose to expose on Saturday night."
Price has been training with former heavyweight champion Lennox Lewis in preparation for his bout with the former world title challenger.
